- Abstract
This paper proposes a novel method for realizing arbitrary fractional divider based on FPGA. Analyzing the limitations of the existing frequency-divided methods, a new model which consists of two-level dividers is put forward. An arbitrary frequency-divided clock output can be obtained by this method approaching 50% of duty cycle. When the division factor is greater than 128, the duty cycle can be very close to 50% of the clock output. This method is proved to be feasible on the FPGA chip of ALTERA.
